Don from Florida

Just spent 2 weeks in Europe with my HJC IS-Max BT helmet and Chatterbox XBi2-H unit. Worked great linked with my Garmin Zumo 660. Told me when every turn was. Only problem was there were so many hairpins with turn instructions the battery only lasted from 9AM to about 4PM. Helmet is a little too noisy at 140KPH to hear the speakers. Other than that worked great.
